Lower legs below the knees are black

Dose anyone know what can cause the lower part of my legs to be black. I am currently on amiodarone (pacerone) and coumadin. I monitor my INR every one to two weeks to keep it at between 2.5 and 3.5. I have a St Jude artificial valve and have been on coumadin for 27 years.
